Cook the Quinoa
During that time you can chop the tomato, the bell pepper and the celery into very small cubes
Also chop the parsley very finely.

Once the Quinoa is fully cooked, let it cool for 30 minutes in the frig.
After 30 minutes put the quinoa into a bowl and mix in the cut vegetables
Pour the olive oil, the red wine vinegar and the salt and pepper mix together well.
You can make this salad in advance, because the more you let it sit the tastier it will get
